Cap01 is no longer available, CAP04  is a replacement

Usage:

You can use Cap01 with Mach3 in 2 ways.

1. You can use as a stand alone THC in Plasma or Oxy-Fuel Cutter applications

2. Together with voltage controlled THC as a IHS (Initial Height Sensor), and Capacitive Limit Switch in Plasma Cutter applications.

Connection:

Sensor connection made via parallel port and requires 2 or 3 inputs.

1. You can use THC UP and THC DOWN inputs for controlling the height by capacitive sensing.

Also connect.Cap01 Down Output  (add simple RC or C filter for PWM version) to the Probe Input shown below.

2. Or connect Cap01 Down Output as a floating switch Probe Input and Up Output as a – Z limit switch in voltage controlled height sensing applications

Configuration:

Config>Ports&Pins>Input Signal>Enable Torch On , Torch Up,  Torch Down and Probe inputs 

Macro:

You need simple macro for M3 (or M03) command . It could be easily edit or create in VB editor or simply copy and paste. Please call for the latest Macro codes.

M3 Code:

Dim PierceHeight, PierceTime, Z_Min_Height, Z_Pos

PierceHeight = GetUserDRO(1000) 
PierceTime = GetUserDRO(1001)

Z_Min_Height= GetUserDRO(1003) 
code "G31Z"&(Z_Min_Height) // This will allow to continuously follow the curve on cutting material
While IsMoving()
Wend

Z_Pos = GetDro(2) 
code "G1Z"&(Z_pos+PierceHeight) // This will allow to rise Piercing level
While IsMoving()
Wend

code "G4P1"
DoSpinCW()
code "G4P"&(PierceTime) // Wait for Piercing. Config>GeneralConfig> check G04 Dwelli in ms  box

G Code 

You don't need cutting height or piercing height in your cam software. 

Delete ALL Z values after M3 command until M5 present.

You only need retract level ( Z ) for Torch moves up between cuts.

Sample G Code

G21 (Units: Metric)
G53 G90 G91.1 G40
G00 X0 Y0 z0
f2000
G01 x10
M3  (Z axe down until cutting height, Up for piercing level, wait for piercing than go)
x130
M5 
g0 z-40 (Retract level between cuts)

m30
